LAMINATED INNER SOLE Charles Morali, Forest Hills, N. Y.

Application June 13, 1955, Serial No. 514,822

1 Claim. (Cl. 315-44) This invention relates to inner soles.

lt is an object of the present invention to provide an inner sole for street wearing shoes which will provide the wearer with a feeling of comfort due to the resilient softness of the construction and which will also act as a shock absorber when walking over rough ground as well as an insulator for wet or worn outer soles.

It is another object of the present invention to provide an inner sole of the above type which will gently grip the foot in place, preventing slippage and the formation of calluses and wherein the inner sole is secured to the outer sole in an improved manner.

Other objects of the invention are to provide an inner sole having the above objects in mind which is of simple construction, has a minimum number of parts, is inexpensive to manufacture and efficient in use.

For other objects and a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing, in which:

Figure 1 is a perspective view of a preferred embodi ment of the present invention;

Fig. 2 is an exploded perspective view of the parts comprising the invention;

Fig. 3 is a fragmentary side view shown partly in elevation and partly in section showing the invention incorporated in a street wearing shoe;

Fig. 4 is an enlarged fragmentary vertical sectional View showing the manner in which the improved inner sole is bonded to the outer sole;

Fig. 5 is a transverse vertical sectional view taken along the line 5-5 of Fig. l;

Fig. 6 is a view similar to Fig. 5 showing the modified form of the present invention;

Fig. 7 is a view similar to Fig. 5 showing a still further modified form of the present invention; and

Fig. 8 is a view similar to Fig. 5 showing a still further modied form of the present invention.

Referring now more in detail to the drawing and more particularly to Figs. 1 through 5, 10 indicates generally an inner sole made up of the layer 11 of fiber, leather or other suitable material, the intermediate layer 12 of sponge rubber or other substance having similar physical properties and the upper layer 13 (Fig. 2) of any suitable fabric. The layers 11, 12 and 13 are secured together by the peripheral parallel rows of stitching 14. The stitching 14 may be straight or zigzag and adds strength to the inner sole as well as forming a better mesh with the glue 15 normally employed to secure the inner sole 10 to the outer sole 16 (Fig. 4). Thus, the stitching 14 provides a protrusion below the undersurface of the inner sole 10 which creates a better bonding effect with the glue 15.

nited States Patent O M 2,784,502 PatentedV Mar. 12, 1957 Referring now particularly to Fig. 6, there is shown a modified form of the present invention indicated generally at 10a wherein the peripheral edges of the sponge rubber layer 12a and fabric covering 13a are bevelled off.

Referring now particularly to Fig. 7, there is shown a still further modified form of the present invention indicated generally at 10b wherein the layers 11, 12 and 13 are secured together by glue or other suitable adhesive means and the stitching 14 is deleted.

Referring now particularly to Fig. 8, there is shown a still further modified form of the present invention indicated generally at 10c wherein the layers 11, 12C and 13a are secured together by means of glue or other suitable adhesive means and wherein the peripheral edges of the layers 12C and 13C are bevelled off.

`In other respects the forms of the invention shown in Figs. 6, 7 and 8 are the same as that shown in Figs. 1 through 5 and like reference numerals identify like parts throughout the several views.

While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claim.

Having thus set forth and disclosed the nature of my invention, what is claimed is:

A multiply stitched inner sole including an outwardly disposed bottom layer, an inwardly disposed top layer presenting a top surface, and an intermediate layer disposed between the top and bottom layers and presenting a downwardly facing surface to the bottom layer in mating engagement therewith, the peripheral edges of the top and intermediate layers having a continuous beveled surface extending uniformly downwardly and outwardly from the top surface of the top layer past the bottom surface thereof and past the top surface of the intermediate layer to a level disposed above the downwardly facing surface of said intermediate layer, and means for securing the three layers into a stitched unit including four rows of stitching extending in parallel, spaced apart manner so that one row extends exclusively upon the top of the top layer within the beveled peripheral portion and through the other layers, and the next outer row extends upon the top of the top layer at the junction thereof with the beveled surface, while the other outer two rows extend upon the beveled surface of the intermediate layer at different portions thereof and with the mentioned next outer row extend through the layers to the bottom surface of the bottom layer.
